Find the System file location via LS

Second, set the boot partition, path, load module, enter the normal mode

Grub rescue> Set root= (HD0,MSDOS1) #设置grub启动分区

Grub rescue> Set prefix= (HD0,MSDOS1)/usr/boot/grub2 #设置grub2启动路径

If the above settings are correct, you can enter the Grub menu of the system normally.
